The problem
Black Friday ads are built to rush you. A "50% off" tag may be off a price nobody paid, the model may be a cheaper version made for the sale, and the return window may be short. It's easy to spend more than you planned on things you didn't need.
Step by step
- 1Write your shopping list and the most you want to spend on each item before the sales start.
- 2When you see a deal, copy the product name, model number, sale price, "was" price and the store's return policy.
- 3Paste them into the prompt below to get a checklist: what to compare, questions about the model number and warranty, and how it fits your budget.
- 4Look up the price history yourself with a price tracker and compare the same model number at two or three other stores.
- 5Buy only what's on your list and under your limit, and save receipts and return dates in one place.
Copy-paste prompt
Help me decide whether this Black Friday deal is worth it. Product: [name and model number]. Sale price: [price] at [store]. "Was" price shown: [price]. Return policy: [paste]. Why I want it: [reason]. My budget for this: [amount]. My full shopping list and budget: [paste]. Give me: (1) what to check about this exact model, including whether it might be a cheaper sale-only version; (2) a short list of things to compare at other stores; (3) questions about warranty and returns; (4) a plain yes, no or wait recommendation based only on my budget and list. Don't make up prices or price history; tell me where to look them up.
Tips and watch-outs
- Compare the exact model number; sale-only models can look the same but have cheaper parts.
- AI can't see live prices or price history, so look those up yourself.
- Set your limit before the sale starts, and check the return window before you buy.
